CHURN AND BUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 604,262, dated May 17, 1898. Applicationfiled November 5, 1897. Serial No. 657,476. (No model.)

To aZZ whom, it may concern:

Be it known that we,W1LLIAM E. PENN and CHARLES S. BROWN, of Lake Mills, in the county of Jefferson and State of Wisconsin, have invented a new and useful Improvement in Churns and Butter-Workers, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

Our invention relates to that class of churns and butter-workers in which a revolving drum and bu tter-workin g rolls therein are employed both for churning and working butter in the same receptacle and by the same devices, the two operations being practically a continuous one; and the-invention is directed to simplifying and improving the construction of the receptacle and devices therein and mounted directly thereon for churning and working butter and to improved practical and suitable means for properly and readily operating the receptacle and related devices.

The invention consists of the mechanism.

and devices, their parts and combinations of parts, as hereinafter described and claimed, or their equivalents.

In the drawings, Figure 1 is an elevation of the front end of the machine. Fig. 2 is a side elevation of the machine. Fig. 3 is a top plan View of the machine, the drum being shown in section to exhibit interior parts, Fig. 4 is a transverse section of the drum centrally. Fig. 5 is an elevation of parts of the driving and operating mechanism, the view being from the inner or drum side of the mechanism, looking away from the drum. Figs. 6, 7, 8, and 9 are details of the construction.

In the drawings, A is a frame of suitable size and form for supporting the operative parts. The receptacle 10, which we have shown as a cylindrical drum, though a rectilinear box or other form of receptacle may be used, is mounted revolubly on the frame, con.- I

veniently by the shaft or arbor 11 at the front end and the arbor 11 at the rear end. The arbor 11 is at its inner end provided with or fixed in a branching flange or spider 12, which is footed against and is secured to the drumhead. The arbors 11 11 are journaled on the frame. The drum is provided with a door. 13

and preferably with a glazed peep-hole 14.

In the drum there are one or more strips 15 15, fixed in the drumheads and serving as dashers and buckets adapted for dashing against the cream during'churning and for elevating the butter by the rotation of the drum during butter-working, and also may serve to elevate and support the butter in convenient position for removing it from the drum after it has been worked through the door 13. One or more bars 16, fixed to the drumheads, may be used for additionally agitating the cream while churning and as complementary sides to the shelves 15 for forming a hopper-like construction for directing the butter onto the rolls; also, there is a set of butter-working rolls 17 17 nearto each other and parallel with and 011 diverse sides of the axis of the drum, mounted revolubly in the heads of the drum, the journals of which rolls atthe front end extend through the head of thedrum and are provided with spur-gears 18 18, that mesh with each other under the spider or between the spider and the head of the drum,as clearlyindicated in Fig. 7. When used as a butter-worker, these rolls revolve inwardly toward each other on that side temporarily at the top, being actuated by means hereinafter described.

For revolving the drum with a constant and moderately-rapid motion for churning the arbor 11 is provided with a spur-wheel19, that meshes with a spur-wheel 20, splined on the driving-shaft 21. This shaft is provided with a belt-pulley 22.

WVhile working butter the drum is rotated a half-revolution intermittentlyto elevate the butter and drop it on the rolls 17, which work the butter by pressure as it passes downwardly between them by their inward revolution. For rotating the drum intermittently the wheel 20 is shifted along on shaft 21 out of mesh with wheel 19 and into clutch with a sprocket-wheel 23, revolubly loose on shaft 21, which wheel 23 carries a belt or sprocketchain 24, running thence on and partially about wheel 25, loose on arbor 11, and between disks 26 26, fixed on arbor 11 near to and on each side of the wheel 25, and thence running about an idle-wheel 27, mounted adjustably on a bracket 28', fixed on the frame, and about another idle-wheel 29, mounted on a stud or pin fixed in the weight-actuated lever 48, pivoted on the frame. The axle-pin 3O ofwheel 27 is adjustable in a slot in bracket 28, being held thereto releasably by a nut, whereby the path of the sprocket-chain or belt on and about the wheel'25 may be regulated. The chain belt 24 is provided with a dog or catch 31, which may consist of a short bar secured transversely thereof to the belt 24 and which extends beyond the sides of the belt and is adapted to and does enter recesses 31 31 (of which there are two diametrically opposite sets) in the disks 26 as it comes opposite there to, and thereby engages the disks, causing them and the drum 10 to rotate a half-revolution at each engagement of the dog with said disks, while the belt travels forward continuously. The length of the belt is such that the dog engages and rotates the disks 26 only after such intervals of time as shall have permitted in the meantime the sufficient operation of the rolls 17 for working the supply of butter in the drum past them.

For revolving the rolls 17 during the butter-working process a spur-Wheel 32, splined on the driving-shaft 21, is shifted on the shaft into the plane of the roll-journal gear-wheels 18 concurrently with the shifting of the driving-wheel 20 into clutch with the sprocketwheel 23, whereby the spur-wheel 32 meshes alternately first with one and then with the other gear-wheel 18 as these gear-wheels are brought thereto by the intermittent and periodic half-revolution of the drum. This shifting of the wheels 20 and 32 concurrently respectively into clutch with sprocket-wheel 23 and gear-wheel 18 is readily accomplished by a shifting bar 33, mounted reciprocally in brackets 34 34 on the frame, the lateral turned ends of the shifting bar being furcate and straddling and riding in grooves therefor, respectively, in the hubs'of wheels 20 and 32. A shifting lever 35, pivoted on the frame and to the bar 33, is adapted for shifting the bar 33 and thereby throwing the wheels 20 and 32 into and out of clutch and mesh, as described. A drop-latch 36, pivoted on the lever 35, engages a bracket 34 (serving as a catch) and locks the bar 33 in position and the wheels 20 and 32 to their'work.

For locking the disks 26 and thereby the drum intermittently against rotation during the operation of working the butter a leverlatch 37, Fig. 5, pivoted medially on the frame, is provided with a notch 38, adapted to receive the pins 39 on a disk 26, severally, being held releasably thereto by the spring 40, whereby the latch 37 is so in engagement with one of said pins 39 that the disk 26 is held against rotation; but the latch 37 is provided with an arm 37 which is arranged to be temporarily engaged at its upper end by the chain-carried dog 31 and be pushed down, thereby carrying that end of the latch 37 away from the pin 39, while at the same time the traveling chain 24, by means of the dog 31, rotates the disk 26, moving the pin 39 away from the recess 38. The dog 31 as it goes down remains in contact with the overturned nd of arm 37 only a brief time, and then thee dog slips off the end of the arm and leaves the latch 37, actuated by the springs 40, to engage the succeeding pin 39 as it comes to the recess 38, thus stopping the rotation of the drum when it has revolved a half-revolution. A bent lever 41 is pivoted near one extremity on the frame and carries an idle-wheel 42, mounted thereon by a stud-pin. The forward end of the lever 41 is arranged to be contacted along the under edge thereof by the pins 39 severally and thereby lifted to such extent and at such time as to hold the idler 42 against and thereby to lift the chain 24 near the disks 26 26 temporarily when approaching the close of each half-revolution of the disks, thereby holding the dog 31 on the moving chain in the recesses 31 and in engagement with the disks 26 until the drum has completed its half-revolution, when the lever 41 drops off the moving pin 39, permitting the chain to fall slightly away from the wheel 25 and sufficiently far to instantly release the dog 31 from engagement with the disks 26 and at the same moment that the other pin 39 comes opposite and enters the recess 38 in the latch 37, thus locking the drum against further revolution until the latch 37 shall be again released from the disk by the succeeding pin 39 pushing down the latch. The idler-carrying lever 41 is provided at its rear end with an inclined or beveled cam 43, so disposed as to engage a pin 44, fixed in theshifting bar 33, and cause the forward end of the lever 41 to be lifted out of the path of the pins 39 when the gear is put in position for revolving the drum for churning.

During a portion of the butterworking operation, while the drum is revolving on its axis, the gear-wheel 32 is not in mesh with either of the wheels 18, being outside their path, and when a wheel 18 comes to the wheel 32, if the ends of opposing teeth should contact, there would be blockingor breaking of the parts, except some part yields, until the complementary teeth and spaces come properly into mesh. To provide for this contingency the driving-shaft 21 at its inner end is mounted in a box 45, that is slidable endwise on the frame, the box and shaft being held yieldingly up to their work by a weighted lever 46, Fig. 8, pivoted in the frame. The box 47, in which the other end of shaft 21 is mounted, is pivoted at one end and has a little play at the other end to provide for this possible slight shifting of the shaft. The furcate ends of the shifting bar 33 are sufliciently loose on the hubs of wheels 20 and 32 to also permit of this movement.
